Copper Foils for Lithium Ion Batteries

In the past two decades with the prevalence of portable consumer electronics, the demand for rechargeable energy storage sources of high energy density and low weight has been growing rapidly. Currently larger applications such as zero emission electric vehicles and satellites put up even more stringent requirements for energy storage devices in both energy density and power density. In all of these applications high performance batteries are more and more desired.
Lithium ion batteries are good materials for this high performance demand. There are different methods and chemicals for the production of lithium ion batteries. A lithium ion battery cell is composed of two electrodes, which are the anode and cathode, a separator, and an electrolyte. Generally, the electrodes are fabricated by applying coating slurry onto a metallic foil. One of the metallic foils that are used in lithium ion battery anode parts is copper foils.
Among different conductive substrates copper is an excellent choice for its high electrical and thermal conductivity, combined with a low economical cost. Copper Foils for Lithium Ion Batteries can be used as current collector in lithium ion batteries. The important property of copper foils is they show high conductivity to minimize battery impedance. Copper foils show heat resistance and it is a desired property for a lithium ion battery to have a long cycle life. Also, copper foils show good tensile strength and elongation properties which prevents cracking when they used in anode part for coating purposes in lithium ion batteries.

Hydroxyapatite Nanopowders and Their Applications

Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4 ) 3 (OH). Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticles (50 nm, 99.95+%)  has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecular or cancellous bone. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. As mentioned before,  Hydroxyapatite Nanopowder  is the main inorganic constituent of bon...

Rundown about Silicon Oxide Wafer

The main insulating material used in micro-technology is Silicon Dioxide, which in chemical symbols is written as SiO2. In semiconductor technology, SiO2 thin film layers are mainly used as dielectric material film in transistors, capacitors (DRAM) or flash-memories. Silicon Oxide Wafers are produced using crystallization, solid state and other ultra-high purification processes such as sublimation. This process forms a cylindrical ingot, which is then sliced and polished to form wafers. Thermal oxide is a kind of "grown" oxide layer, compared to CVD deposited oxide layer, it has a higher uniformity, and higher dielectric strength, it is an excellent dielectric layer as an insulator . In most silicon- based devices, thermal oxide layer play an important role to pacify the silicon surface to act as doping barriers and as surface dielectrics. The simplest way to produce an insulating silicon oxide layers (SiO2) on silicon wafers is to oxidize silicon with oxygen, which ...
